Latest Patch - SK lifetap buff spells not working

[AndMetal]

I did some checking, and it looks like we may be adding too much to the modifier from the spell:

[COMBAT__PROCS] Xamlagar: Proc chance 0.11 (0.07 from bonuses)
[COMBAT__PROCS] Xamlagar: Spell proc 0 failed to proc 3129 (10.7125 percent base + 100 percent spell mod = 10 percent chance)
[COMBAT__PROCS] Xamlagar: Spell proc 1 procing spell 6908 (10.7125 percent base + 500 percent spell mod = 53 percent chance)
[COMBAT__PROCS] Xamlagar: Proc chance 0.11 (0.07 from bonuses)

The first one is Call of Sky, which has a modifier of 0 (so it should be 100%). The second is Spirit of the Puma, which has a modifier of 400 (so it should be 400%).

I'm just not really sure if it would be better to put the check in Mob:TryWeaponProc() or Mob:AddProcToWeapon() rather than Mob:SpellEffect().
